Evaluación sismo resistente de una vivienda de dos plantas de hormigón armado ubicada en la ciudad de Machala

Abstract

In this work, the structural design of a two-story reinforced concrete house will be evaluated in order to check if it complies with the seismic design resistance established by the NEC-SE-DS standard. The house was built in 1996 under the Ecuadorian Construction Code and is located in the city of Machala. We started with the compilation of the plans that were used for the construction of the house, then an on-site visit was made to make the survey and verify that there are no changes in the construction process, and also that the sections comply with the NEC-SE-HM standard. The structural modeling was erformed with ETABS software, which gives us as a result that the period of the structure, the column demand-capacity, D,C and the drift of the structure is greater than what is indicated in the NEC-SE-DS standard. The ribbed slab and footing are also calculated manually, thus obtaining a total structural analysis of the house to answer the questions of compliance and the possible need for structural reinforcement.
